To aZZ'w/zom it mail concern:

Be it known that l Gnome FowLnn, a citizen of the United States, residing at 17:28 Connor Ave, in the city of Joplin, in the county of Jasper, in the State of Mis- SOlll'i. have invented new and useful inn provements in Pistons for lnternal-Conibus tion Engines, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to improvements in pistons for internal combustion engines, in which the piston is made of two sections secured together by bolts or screws in such manner as to admit of adjustment.

The objects of my invention are: first, to eliminate piston slap, a noise familiar to those versed in engines, without using a new piston; second, to produce a. piston that will wear longer; third, to make an adjustable piston.

In the drawing, A represents the main section of the piston, B is a detachable section secured to the main section A by bolts or screws which are designated by the letter (3 in drawing. These bolts or screws are recessed within the circumference of the pis ton as shown in the drawing. Referring to the. drawing. the dotted circle E indicates the position of the piston pin. Sections A and B of the piston are shown as joined together in a plane which passes through the piston pin. This piston is cylinder shaped.

In my invention due consideration has been given to simplicity of design and low Specification of Letters Patent.

production cost. After the edges of sections A and B have been machined, these sections are joined together, then the piston is finished as though it were a singie piece, reamed tor the piston pin and grooved for a pluraiity of rings.

(En the piston of an internal combustion engine wear is greatest upon the: surfaces represented by the extreme rig and left of the drawing,

and decreases to the ininimum toward the part of the piston repre sented by the center or? the-drawing. in my invention this wear is eliminated inser*- ing metal shims between sections A and B equal to the amountof such Wear.

claim:

A piston comprising a substantially cylindrical piston head, a substantially semi-cylindrical portion integral therewith and forming a part of the body of the piston, a second substantially semi-cylindrical portion, said semi-cylindrical portions being provided with recesses adjacent the meeting edges and openings adapted to register with each other and bolts arranged in said openings to retain said second semi-cylindrical portions in position, the semi-cylindrical portions being secured to each other in a plane substantially in alinementi with the plane of the center of the wrist pin.
